We have extended the SX20 12x camera using the cable that came with it, then extending the RJ end that connects to the camera with standard Cat6 cable, and similar with the HDMI - by using an HDMI extension (or for longer distances, HDMI extenders). No need to use the special split cables.
Note: if you move the camera a long distance away, then the voltage loss over the control cable may be too much to be able to power the camera, so you will need to power the camera with a separate power supply (PSU-12VDC-40W2=)
